4. Likarolo tse ikhethang tsa mohala oa ho hanyetsa Karma
1) Ho qala ka Nickel Chromium terata ea mocheso oa motlakase oa Motlakase oa Sehlopha sa 1, re ile ra nkela sebaka se seng sa Ni ka Al le likarolo tse ling, 'me kahoo ra finyella boitsebiso bo nepahetseng ba ho hanyetsa ka mocheso o ntlafetseng oa mocheso le matla a motlakase a mocheso khahlanong le koporo.
Ka tlatsetso ea Al, re atlehile ho etsa hore molumo oa resistivity 1.2 o be moholo
ho feta Nickel Chromium terata ea mocheso ea motlakase ea Sehlopha sa 1 le matla a thata ka makhetlo a 1.3.
2) Coefficient ea bobeli ea mocheso β ea Karmalloy terata KMW e nyane haholo, - 0.03 × 10-6/ K2,
'me mocheso oa mocheso oa ho hanyetsa o fetoha hoo e batlang e le mola o otlolohileng ka har'a mocheso o pharaletseng.
Ka hona, mocheso oa mocheso o behiloe ho ba karolelano ea mocheso pakeng tsa 23 ~ 53 ° C, empa 1 × 10-6 / K, karolelano ea mocheso pakeng tsa 0 ~ 100 ° C, le eona e ka 'na ea e-ba 1 × 10-6 / K.
ho amoheloa bakeng sa coefficient ea mocheso.
3) Matla a motlakase khahlanong le koporo pakeng tsa 1 ~ 100 °C le ona a nyenyane, ka tlase ho + 2 μV/K, 'me a bontša botsitso bo babatsehang ka nako ea lilemo tse ngata.
4) Haeba sena se tla sebelisoa e le thepa ea ho hanyetsa ka mokhoa o nepahetseng, phekolo ea mocheso o tlaase oa mocheso o hlokahalang ho felisa ho sotha ho sebetsa joalo ka tabeng ea terata ea Manganin CMW.
